Keep it PG-13 or lower, kthnx.

I would listen to the youngster and just ignore the logic. Pokemon logic isn't supposed to make sense in the real world - it's a game. A game based around people who catch and battle animals with infeasible powers. It's just silly to take anything from the game seriously.

Let's look at the move itself, or to be exact, it's description. To paraphrase it, the user wags its tail cutely. The opponent's pokemon, upon seeing this, thinks the user of the move isn't is tough as it thought. Thus, it lets it guard down, thereby lowering its defense.
